Peel the onion and garlic, and cut the jalapeño. Choose to make it spicy or not, leaving the seeds or removing them.
In your blender, combine tomatoes (with juice), jalapeño, onion, garlic, cilantro, cumin, paprika, lime juice, salt, pepper, and sugar.
Give it a few good pulses till smooth and yet lively. You do not want it to be thin and watery.
Dip in a chip (this is the perk of the chef). Add salt, lime, or spice when necessary.
To add more heat and a little cooked flavor, simmer the salsa in a saucepan for 10 minutes and cool.
Allow it to rest in the refrigerator for at least 1 hour. The tastes mix and blend beautifully.
Accompanied with tortilla chips, tacos, enchilada--or to tell the truth, just leave it in the fridge as your week-long flavor enhancer.
